Description

  The present invention relates to a stacking device used in, for example, a manufacturing process of a stacked battery.

  A laminate constituting a laminated battery or the like is formed by alternately laminating a positive electrode foil coated with a positive electrode active material and a negative electrode foil coated with a negative electrode active material via a separator made of an insulating material. I have.

  2. Description of the Related Art Conventionally, as an apparatus for manufacturing the above-mentioned laminated body, a laminating apparatus in which a sheet body such as a positive electrode foil, a negative electrode foil, and a separator is sequentially conveyed and mounted on a predetermined stage by a predetermined conveying apparatus is known.

  In such a laminating apparatus, the upper surface of the laminated body is normally held down by a pressing claw so that the stacked sheet bodies do not shift during the work. Then, when a new sheet body is conveyed and placed by the conveying device on the upper surface of the stacked body in such a state, the holding claw rises by a predetermined amount while the conveying device presses the new sheet body from above. Swivels horizontally. Thereby, the holding claw can be retracted from the laminate without rubbing the upper surface of the laminate. When the holding claw retreats from the stacked body, the edge portion of the sheet body that has been placed on the holding claw is straightened and is in a state of being overlapped with the upper surface of the stacked body. Thereafter, the holding claw is lowered, and the upper surface of the stacked body is pressed again from above the newly placed sheet body.

  Here, conventionally, regardless of the thickness of the laminated body that increases with the progress of the laminating step, the holding claw always rises to a constant height position, corresponding to the height position where the laminated body finally reaches. Was configured as follows.

  Therefore, in the initial stage of the laminating step in which the thickness of the laminate is small, the amount of rise when the holding claw rises from the upper surface of the laminate becomes large. In a case where the amount of rise of the holding claw is large, when the holding claw rises, the edge of the sheet member placed thereon is lifted greatly. That is, the edge of the sheet body placed on the holding claw is greatly deformed, and various problems may occur.

  For example, when the sheet body placed on the holding nail is an electrode foil, the electrode foil may be damaged. Also, regardless of the type of the sheet, if the edge of the sheet placed on the holding claw is significantly deformed, the deformed portion is turned up and bent, and the next sheet is stacked. There is also a risk. When such various inconveniences occur, there is a possibility that the quality of the product is deteriorated, for example, a short circuit is caused.

  In view of this, in recent years, there is a technique of lowering the stacking stage in accordance with the progress of the stacking process so that the height position of the upper surface of the stack is constant in order to suppress the relative amount of rise of the presser claws ( For example, see Patent Document 1). Thereby, even in the initial stage of the laminating step, since the relative amount of rise of the holding claw can be reduced, it is possible to laminate the sheet bodies without greatly deforming the sheet body placed thereon. it can.

  Further, in recent years, there is a laminating apparatus adopting a turntable method that can speed up laminating work and improve productivity (for example, see Patent Document 2). In such a stacking apparatus, a stacking operation can be performed simultaneously at a plurality of working positions while rotating a turntable on which a plurality of stacking stages are arranged and intermittently moving each stacking stage to a plurality of working positions.

  However, if the height adjusting mechanism of the stacking stage according to Patent Document 1 is to be employed in the turntable type stacking device according to Patent Document 2, a plurality of stacking stages arranged on the turntable are required. It is necessary to provide a height adjustment mechanism for each.

  Each height adjustment mechanism that moves the entire stacking stage may be large and heavy. Therefore, when the height adjusting mechanism is provided for a plurality of stacking stages, the turntable as a whole increases in size, and its weight also increases in proportion to the number of stacking stages. As a result, the operability of the turntable may be reduced, and the productivity may be reduced.

  The present invention has been made in view of the above circumstances, and has as one of its main objects to provide a laminating apparatus capable of improving productivity while suppressing quality deterioration of a laminated body.

  Hereinafter, each means suitable for solving the above-described problem will be described in terms of items. In addition, the function and effect peculiar to the corresponding means will be added if necessary.

Means 1. A laminating apparatus for manufacturing a laminate in which a positive electrode foil coated with a positive electrode active material and a negative electrode foil coated with a negative electrode active material are alternately laminated via a separator made of an insulating material. ,
In addition to being provided so as to be intermittently rotatable about an up-down direction as an axis, a plurality of laminating portions (lamination stages) for laminating the positive electrode foil, the negative electrode foil and the separator are provided at a plurality of positions, and the laminating portions are respectively laminated by a plurality of A turntable that can be moved intermittently to the working position,
Provided corresponding to the plurality of laminating operation positions, respectively, a transporting means capable of transporting and placing a sheet body including the positive electrode foil, the negative electrode foil or the separator to the laminating portion located at the laminating operation position,
A pressing member for pressing the laminated body laminated on the laminated portion from above,
The displacement member is configured to be capable of performing a displacement operation in the vertical direction and a displacement operation in the horizontal direction of the pressing member, and the new sheet member is placed by the transporting means on at least the stacked body pressed by the pressing member. In this case, the pressing member is raised and displaced in the horizontal direction, and thereafter, a pressing member driving unit capable of executing an operation of pressing the stacked body from above the newly placed sheet body,
Height adjusting means for adjusting a height position (amount of lifting of the pressing member) at which the pressing member is raised in accordance with a height (amount of stacking) of the stacked body laminated on the stacking portion ;
The height adjusting means,
An action section (action mechanism section) acting on the holding member;
A drive section (drive mechanism section) that operates based on control by predetermined control means and that can adjust the position of the action section;
A laminating apparatus characterized in that at least the drive section is provided at a position separated from the turntable (a position that does not rotate with the turntable) .

  According to the above-mentioned means 1, when a new sheet body is placed on the laminated body pressed by the pressing member, and when the pressing member is raised, the height position at which the pressing member is raised is set to the height of the laminated body. It can be adjusted accordingly.

  Thereby, for example, even in the initial stage of the laminating step in which the height of the laminate is low, the relative rise of the pressing member with respect to the upper surface of the laminate can be relatively reduced. Since the rising amount of the pressing member is reduced, the degree of turning of the edge of the sheet member placed on the pressing member can be reduced. In other words, the sheet body can be laminated on the laminate without significantly deforming the sheet body placed on the pressing member. As a result, the quality of the laminate can be improved.

  In particular, in this means, since the height of the holding member is adjusted instead of the stacking section (stacking stage), the mechanism relating to the height adjustment means does not increase in size, and the weight of the apparatus can be reduced. it can. Even if at least a part of the mechanism relating to the height adjusting means is provided on the turntable, the weight of the turntable can be suppressed. As a result, a decrease in the operability of the turntable can be suppressed, and a decrease in productivity can be suppressed.

  Generally, when a controlled device such as the drive unit is installed on a turntable that is driven to rotate, a controlled device installed on the turntable and a control device (control means installed outside the turntable) ) Are connected via a slip ring or the like.

  Therefore, when installing a plurality of drive units on a turntable, a large number of wirings connecting the plurality of drive units to an external control device, a slip ring or the like having the same number of terminals as the number of these units. It is necessary to connect via a wire, and the wiring may be extremely complicated.

  In addition, since the number of wirings increases in proportion to the number of stacked portions, wiring may be difficult depending on the number of stacked portions. Usually, since a plurality of pressing members are provided for one laminated portion, if the above-mentioned driving portions are individually provided corresponding to each of these, the number of wirings increases geometrically.

On the other hand, according to the above-described means 1 , at least the drive unit controlled by the control means of the mechanism relating to the height adjustment means is provided at a position separated from the turntable, thereby facilitating and simplifying wiring. Can be achieved.

  Further, when a mechanism relating to the height adjusting means of the holding member is provided on the turntable, it is necessary to provide a mechanism corresponding to each of the plurality of laminated portions arranged on the turntable. For example, when twelve laminated portions are provided on the turntable, it is necessary to provide mechanisms corresponding to the height adjusting means of the pressing member at twelve locations.

  On the other hand, according to the present means, among the mechanisms relating to the height adjusting means, at least the drive units controlled by the control means may be provided in the number equal to the number of the stacking operation positions. However, in the case where a mechanism (drive unit) relating to the height adjustment means is individually provided for each of the plurality of holding members provided for one laminated portion regardless of whether it is on a turntable or outside, It is necessary to provide only a multiple of.

  Usually, in a turntable type laminating apparatus, since there is provided an unloading operation position and the like for taking out a completed laminate from the turntable, the number of laminating operation positions for performing the laminating operation is on the turntable. It is smaller than the number of laminated portions provided. As a result, according to this means, the number of parts can be reduced and the configuration can be simplified.

  Further, when the sheet body is a separator, even if a large deformation is applied to the edge portion, the sheet body is hardly damaged like the positive electrode foil and the negative electrode foil. (At least the drive unit) can be omitted. If the mechanism relating to the height adjusting means is provided only in the laminating operation position where the positive electrode foil and the negative electrode foil are laminated as described above, the number of installation locations can be greatly reduced.

  In addition, as the "position separated from the turntable", for example, a fixed shaft provided so as not to be displaceable along the rotation axis of the turntable, a base below the turntable, etc. A fixed position that is not displaced with respect to the stacking operation position in a plan view.

  The holding mechanism 30 includes four holding members 31A, 31B, 31C, 31D provided corresponding to the four corners of the stacking stage S (pallet P, stacked body 4). The four holding members 31A, 31B, 31C, 31D according to the present embodiment are configured to move in synchronization. Hereinafter, the holding members 31A, 31B, 31C, and 31D may be collectively referred to as a "holding member 31" unless it is particularly necessary to distinguish them.

  Here, the configuration of the holding member 31 will be described in detail with reference to FIGS. The holding member 31 has a shaft portion 40 provided rotatably about the vertical direction (the depth direction of the paper surface of FIGS. 4 to 9) and displaceable in the vertical direction, and a flat surface provided on the upper portion of the shaft portion 40. It has a base pentagonal base 41, and four flat holding claws 42A, 42B, 42C, 42D extending from four of the five sides of the base 41 radially outward of the shaft 40. ing. Hereinafter, when it is not particularly necessary to distinguish them, the holding claws 42A, 42B, 42C, and 42D may be collectively referred to as a "holding claw 42". The base 41 and the holding claws 42 constitute a holding member in the present embodiment.

  The shaft portion 40 of the holding member 31 is disposed on one side α of two orthogonal sides α and β constituting each corner of the four corners of the stacked stage S [in the present embodiment, among the four sides of the stacked stage S, Two sides along the left-right direction in FIG. 3 parallel to the direction of movement of the suction unit 17 are referred to as sides α]. In other words, of the four sides of the stacking stage S, one pair of the two holding members 31 (the shaft portions 40) is arranged along two sides α opposed to each other across the guide rail 15 of the transport device 14. I have.

  The holding member 31 (shaft portion 40) is configured to be rotatable and vertically movable by a predetermined driving mechanism (see FIG. 10 and the like) described later. Thereby, the holding claw 42 can be turned in the horizontal direction or moved up and down.

  However, in the present embodiment, the holding members 31 are configured to rotate in only one predetermined direction. More specifically, of the pair of holding members 31, the holding members 31A and 31C located on the left side toward the side surface (side α) of the lamination stage S rotate counterclockwise in plan view, and move to the right. The positioned holding members 31B and 31D rotate clockwise in plan view.

  In the present embodiment, the holding member 31 is configured to be intermittently rotatable in the one direction by 72 ° (360 ° / 5). Thus, the holding claws 42A, 42B, 42C, 42D can be sequentially moved in this order from the first stop position X1 to the fifth stop position X5.

  That is, of the one set of the holding members 31, the holding claws 42A, 42B, 42C, 42D and the stop positions X1, 31A are different between the left holding member 31A (31C) and the right holding member 31B (31D) having different rotation directions. The order of X2, X3, X4, X5 is reversed (see FIG. 9).

  More specifically, of the five sides of the base 41, the holding claw 42A is provided on the first side in the anti-rotation direction from the side where the holding claw 42 is not provided (hereinafter, referred to as a blank portion K). Further, from the blank portion K, a pressing claw 42B is provided on a second side in the anti-rotation direction, a holding claw 42C is provided on a third side in the counter rotation direction, and a fourth side is provided in the counter rotation direction. Is provided with a holding claw 42D.

  Therefore, in the present embodiment, the holding claws 42B are arranged at intervals of 72 ° in the circumferential direction of the shaft portion 40 from the holding claws 42A, and the intervals of 72 ° in the circumferential direction of the shaft portion 40 from the holding claws 42B. The holding claw 42C is arranged, and the holding claw 42D is arranged at an interval of 72 ° from the holding claw 42C in the circumferential direction of the shaft portion 40. The holding claw 42D is arranged 144 ° in the circumferential direction of the shaft portion 40 from the holding claw 42D. The configuration is such that the holding claws 42A are arranged at intervals.

  Then, when the holding claw 42 stops at the first stop position X1, the extending direction of the holding claw 42 and the side α of the stacked stage S with which the shaft portion 40 faces are orthogonal to each other in plan view.

  In addition, when one holding claw 42 is stopped at the first stop position X1 in each holding member 31, the other three holding claws 42 are stopped at positions where they do not overlap with the stacked body 4 in plan view. Is configured. That is, when the holding claw 42 is at the second stop position X2 to the fifth stop position X5, the holding claw 42 does not overlap with the stacked body 4 in a plan view.

  Therefore, when pressing the stacked body 4 placed on the stacking stage S (pallet P), one of the two orthogonal sides α and β constituting the corner portion near the corner portion of the stacking stage S near the corner portion. The side of the stacked body 4 parallel to the side α is pressed by one pressing claw 42 stopped at the first stop position X1.

  In addition, when the shaft portion 40 moves up and down, the position of the pressing claw 42 in the up-down direction can be brought into contact with the separated position (see FIGS. 12 and 13 and the like) separated upward from the laminate 4. It can be displaced to the contact position (see FIGS. 10, 14 and the like). In FIGS. 10 to 15, the stacked body 4 is illustrated in a simplified manner, with the gaps between the sheets stacked on the stacking stage S (pallet P).

  When the pressing claw 42 that has been pressing the stacked body 4 at the first stop position X1 is moved to the second stopping position X2, the first claw 42 is slightly lifted up from the stacked body 4 in the first stop position. The turning movement is performed from the stop position X1 to the second stop position X2.

  At this time, in this embodiment, the tip 43 of the pressing claw 42 is at least one side of the two sides forming each corner of the stacked body 4 that the pressing claw 42 pressed at the first stop position X1. It turns so as to pass over the other side (side parallel to the side β of the stacking stage S) different from the (side parallel to the side α of the stacking stage S).

  Further, in the present embodiment, the types of the holding claws 42A, 42B, 42C, 42D for holding the stacked body 4 according to the type of the sheet body placed on the uppermost surface of the stacked body 4 (on the pallet P at the start of stacking). Are switched.

  More specifically, when the sheet body placed on the uppermost surface of the laminated body 4 is the negative electrode foil 1, the holding claw 42A among the four holding claws 42A to 42D is used. Hereinafter, the “holding claw 42A” is referred to as a “negative electrode holding claw 42A”.

  When the sheet placed on the uppermost surface of the laminate 4 is the separator 2 laminated on the upper side of the negative electrode foil 1, of the four retainers 42A to 42D, the retainer 42B is used. Hereinafter, the “pressing claw 42B” is referred to as a “negative electrode upper pressing claw 42B”.

  When the sheet placed on the uppermost surface of the laminate 4 is the positive foil 3, the holding claw 42C is used among the four holding claws 42A to 42D. Hereinafter, the “pressing claw 42C” is referred to as a “positive electrode pressing claw 42C”.

  When the sheet placed on the uppermost surface of the stacked body 4 is the separator 2 stacked on the upper side of the positive electrode foil 3, the holding claw 42D is used among the four holding claws 42A to 42D. Hereinafter, “pressing claw 42D” is referred to as “positive electrode upper pressing claw 42D”.

  Next, a driving mechanism for driving each holding member 31 will be described with reference to FIGS. Such a driving mechanism constitutes a pressing member driving unit in the present embodiment.

  In the present embodiment, the four holding members 31A, 31B, 31C, and 31D are configured so that the four holding members 31A, 31B, 31C, and 31D move synchronously by interlocking the four driving mechanisms. .

  As shown in FIG. 10 and the like, the shaft portion 40 is supported by a support portion 50 provided on a side surface of the lamination stage S. More specifically, an insertion hole 51 is formed in the support portion 50 along the vertical direction, and the shaft portion 40 is inserted here. As a result, the shaft 40 is rotatable and vertically movable with respect to the support 50.

  A cylindrical rotation regulating cam 55 is attached and fixed to the upper surface of the support part 50 with the shaft part 40 inserted therethrough. The rotation restricting cam 55 is provided with five U-shaped grooves 56 formed at intervals of 72 ° in the circumferential direction so as to cut out the upper edge thereof.

  Correspondingly, a rotation regulating projection 57 projecting radially outward and being insertable into the groove 56 is formed on the peripheral surface of the shaft 40. However, the rotation restricting protrusion 57 is provided only at one position in the circumferential direction of the shaft 40. When the rotation restricting projection 57 is inserted into one of the five groove portions 56, the pressing claw 42 is stopped at any one of the stop positions X1 to X5.

  Further, the shaft portion 40 is provided with a flange portion 60 formed to protrude radially outward from the peripheral surface at a position below the support portion 50. A coil spring 61 is mounted between the flange portion 60 and the lower surface of the support portion 50. With such a configuration, the shaft portion 40 is pressed down, and the pressing body 42 can press the laminated body 4.

  On the other hand, a cylindrical operating cam 63 is disposed below the shaft portion 40. More specifically, the operation cam 63 is provided at a position below the turntable 6, and is configured to be rotatable around a vertical direction and vertically movable by a driving unit (not shown). However, the operation cam 63 and its driving means are provided only in the stacking operation positions R2 to R9 and the unloading operation position R11 except for the taking-in operation position R1 and the blank positions R10 and R12 which do not require the displacing operation of the holding member 31. ing.

  An insertion hole (not shown) is formed in the turntable 6 at a position below the shaft portion 40 so as to correspond to the operation cam 63 and extend vertically. As a result, the operation cam 63 can come and go on the turntable 6, and the power can be transmitted to the shaft portion 40.

  The driving means for driving the operation cam 63 includes a direct-acting type hydraulic cylinder (vertical drive means) for vertically moving the operation cam 63 and a rotary cylinder (rotation drive means) for rotating the operation cam 63. ) Are combined as an example. Of course, the configuration of the driving means relating to the holding member 31 (the operation cam 63) is not limited to this, and another driving means may be employed.

  In addition, a pair of cam surfaces 64 are formed on the upper portion of the operation cam 63 so as to cut out the upper edge thereof. The pair of cam surfaces 64 are formed at positions facing each other across the axis of the operation cam 63, that is, at intervals of 180 ° in the circumferential direction.

  Each of the cam surfaces 64 is formed in a range corresponding to a central angle of 72 ° in the circumferential direction of the operation cam 63 and has a predetermined rotation direction (for example, a counterclockwise direction for the holding member 31A and a clockwise direction for the holding member 31D). It has a slope shape that slopes from top to bottom along.

  Correspondingly, a pair of operating pins 65 are provided at the lower end of the shaft portion 40 so as to protrude radially outward and contact the cam surface 64 of the operating cam 63. The pair of operating pins 65 are formed at positions facing each other across the axis of the shaft portion 40, that is, at intervals of 180 ° in the circumferential direction.

  In the present embodiment, the pressing claw 42 is configured to be vertically displaceable with respect to the shaft portion 40. Hereinafter, such a configuration will be described in detail. The base 41 has an insertion hole (not shown) through which the shaft 40 is inserted. The inner diameter of the insertion hole is substantially the same as the outer diameter of the shaft portion 40. Thereby, the base 41 is in a state in which the base 41 can be slid and displaced with respect to the shaft 40 in the vertical direction.

  However, the base 41 is in a state where it cannot be displaced in the circumferential direction of the shaft 40. More specifically, a keyway (not shown) is formed on the upper outer peripheral surface of the shaft portion 40 along the axial direction (vertical direction). Correspondingly, a key (not shown) is formed on the inner peripheral surface of the base 41 (insertion hole), protruding radially inward and formed along the up-down direction. When the key on the side of the base 41 is fitted into the key groove on the side of the shaft 40, the base 41 (pressing claw 42) can be displaced relative to the shaft 40 in the axial direction and the circumferential direction. In a state in which it cannot be displaced.

  Further, the shaft portion 40 is provided with a flange portion 67 which is formed at a position higher than the rotation regulating protrusion 57 so as to protrude radially outward from a peripheral surface thereof. A coil spring 68 is mounted between the flange 67 and the lower surface of the base 41. Due to the urging force of the coil spring 68, the base 41 and the pressing claw 42 are pushed upward. The coil spring 68 constitutes an urging means in the present embodiment.

  However, a stopper (not shown) that restricts the movement of the key on the base 41 is provided at the upper end of the key groove on the shaft 40. Accordingly, the base 41 is normally urged against the stopper by the urging force of the coil spring 68. That is, when the shaft portion 40 is pressed down by the urging force of the coil spring 61 and the laminated body 4 is pressed by the pressing claw 42, the base portion 41 is in a state of being urged by the stopper.

  Next, the operation of the driving mechanism of the holding member 31 will be described in detail with reference to FIGS.

  When the turntable 6 rotates intermittently and the stacking stage S stops at the stacking operation positions R2 to R9, the holding member 31 is in a stopped state.

  While the holding member 31 is stopped (while each holding claw 42 is stopped at one of the stop positions X1 to X5), the operation cam 63 is stopped at the reference position below the turntable 6. In this state, the shaft portion 40 is pressed down by the urging force of the coil spring 61. As a result, the stacked body 4 is pressed by the holding claws 42 stopped at the first stop position X1. In the example illustrated in FIG. 10, the negative electrode pressing claw 42 </ b> A stopped at the first stop position X <b> 1 is in a state of pressing the laminate 4 (negative electrode foil 1).

  Then, when a new sheet member is conveyed to a position above the stacking stage S by the suction unit 17, the operation cam 63 rises to near the lower end of the shaft unit 40, and enters a standby state (see FIG. 10).

  Subsequently, the suction unit 17 is lowered, and a new sheet body is placed on the upper surface of the stacked body 4 (see FIG. 11). Here, the edge of the sheet body that protrudes outward from the peripheral edge of the suction unit 17 is placed on the holding claws 42 that hold the upper surface of the stacked body 4. Further, the upper portion of the shaft portion 40 is inserted into the insertion hole 39a of the regulation piece 38 (regulation protrusion 39) provided in the suction portion 17.

  When the sheet is placed on the upper surface of the stacked body 4, the operation cam 63 starts to rise. When the operation cam 63 (cam surface 64) comes into contact with the operation pin 65 of the shaft portion 40, the shaft portion 40 is pushed up by the operation cam 63.

  As a result, the pressing claw 42 moves upward, and at the first stop position X1, the pressing claw 42 is separated from the stacked body 4 and the edge of the sheet body placed thereon is lifted. However, at the beginning of the rise, the state in which the rotation restricting projection 57 is inserted into the groove 56 of the rotation restricting cam 55 is maintained, and the shaft 40 does not rotate. Does not change.

  Further, as the shaft portion 40 is pushed up, the shaft portion 40 is inserted into the insertion hole 39a of the restricting piece 38 (the restricting protrusion 39), and the holding claw 42 (the base 41) of the restricting protrusion 39 is moved. Contact the lower end.

  From here, when the shaft portion 40 is further pushed up, the urging force of the coil spring 68 is kept in a state where the height position of the holding claw 42 (the base portion 41) is kept constant by the regulating piece 38 (the regulating protrusion 39). , Only the shaft portion 40 is pushed up. That is, while the holding claw 42 (base 41) and the shaft 40 are relatively displaced in the vertical direction, only the shaft 40 is pushed up by the operation cam 63 to a predetermined height position. In the present embodiment, the amount by which the shaft portion 40 is raised by the operation cam 63 is always constant and does not change.

  As shown in FIG. 10, the lower end of the regulating piece 38 (the regulating protrusion 39), that is, the holding claw 42, is positioned from the lower surface of the attracting portion 17 (the attracting plate 19), that is, the position in contact with the uppermost surface of the laminate 4. The distance T to the position where the (base 41) abuts is constant. Accordingly, the height position of the holding claw 42 is increased each time a sheet body is newly placed, but the amount of rise of the holding claw 42 from the uppermost surface of the stacked body 4 is always constant.

  In addition, the rising amount of the holding claw 42 can be arbitrarily set by the rising amount of the shaft portion 40, the protrusion amount of the regulating protrusion 39, and the like. However, in the present embodiment, the holding claw 42 is The rising amount is set to be always constant.

  When the shaft portion 40 is pushed up to a predetermined height position, the rotation regulating projection 57 comes out of the groove 56 of the rotation regulating cam 55 (see FIG. 12). In such a state, the rotation of the shaft portion 40 is allowed, so that the position of the operation pin 65 moves along the cam surface 64 of the operation cam 63 as the operation cam 63 moves upward. That is, the shaft portion 40 rotates in one predetermined direction (for example, the counterclockwise direction for the holding member 31A and the clockwise direction for the holding member 31D), and each of the holding claws 42 (the base 41) is adjusted to the regulating piece 38 (the regulating protrusion 39). ), And turns horizontally at the level where it abuts.

  As a result, at the first stop position X1, the holding claw 42 retreats from the stacked body 4 without rubbing against the upper surface of the stacked body 4, and the edge of the sheet body that has been placed on the holding claw 42 until then. Extend straight and overlap the upper surface of the laminate 4.

  Then, when each of the holding claws 42 has turned 72 ° in the circumferential direction of the shaft portion 40, the operating pin 65 reaches the lower end of the cam surface 64, and the turning movement of each holding claw 42 stops (see FIG. 13). .

  Here, when the operation cam 63 is lowered, the shaft portion 40 is pushed down by the urging force of the coil spring 61. As a result, the rotation restricting projection 57 is inserted into the groove 56 adjacent to and different from the groove 56 of the rotation restricting cam 55 located before the turning movement. That is, each holding claw 42 descends and stops at the next stop position X1 to X5 different from the stop positions X1 to X5 located before the turning movement (see FIG. 14).

  As a result, the stacked body 4 is pressed by the holding claws 42 stopped at the first stop position X1. In the example shown in FIG. 14, the negative electrode upper separator pressing claw 42B stopped at the first stop position X1 is in a state of pressing the stacked body 4 (separator 2).

  In this state, the suction by the suction unit 17 is stopped to release the suction of the sheet member. Then, after the suction portion 17 is separated upward (see FIG. 15), the operation cam 63 returns to the reference position below the turntable 6.

  At the same time as the operation cam 63 returns to the reference position, the driving means is driven to rotate by 72 ° in a predetermined direction (for example, a counterclockwise direction for the holding member 31A and a clockwise direction for the holding member 31D). Thereby, the relative positional relationship between the operation cam 63 (cam surface 64) and the operation pin 65 of the shaft portion 40 in the circumferential direction becomes the positional relationship in the standby state (see FIG. 10).

  By repeating the above-described series of operations, each holding claw 42 can be turned by 72 ° in one predetermined direction. However, in the present embodiment, when the “positive separator upper holding claw 42D” is turned from the first stop position X1 during the laminating operation (except after the completion of the laminating operation), the above-described operating pin 65 is At a stage prior to the timing of reaching the lower end (see FIG. 13), the operation cam 63 is rotated by 72 ° in a predetermined direction (for example, counterclockwise for the holding member 31A and clockwise for the holding member 31D). Thus, the holding pawls 42 can be turned by an additional 72 ° without being stopped at the position where the holding claws 42 have been turned by 72 °.

  In the present embodiment, the timing at which the “positive separator upper holding claw 42D” is pivoted by 144 ° from the first stop position X1 is determined by the negative electrode foil placement device 11A during the laminating operation (except at the start of laminating). There is a case where the negative electrode foil 1 is transported and placed on the negative electrode foil 1 or a case where the negative electrode foil 1 is transported and placed on the laminating work position R6 by the negative electrode foil placing device 11E.

  When the stacking operation of the stacked body 4 is performed at the unloading operation position R11 after the completion of the lamination, the “positive separator upper holding claw 42D” is moved from the first stop position X1 to the predetermined one direction in the same manner as in other cases. ° to be moved.

  Next, the flow of the laminating operation by the laminating apparatus 5 will be described in detail along the flow of one pallet P. In the present embodiment, the laminate 4 is completed by repeating the lamination process performed while the turntable 6 makes one rotation a predetermined number of times.

  First, the pallet P is arranged on the predetermined stacking stage S on the turntable 6 located at the intake work position R1 by the intake work unit 7 at a predetermined timing based on the data table.

  After that, the pallet P moves to the stacking operation position R2 by rotating the turntable 6 by 30 °. When the pallet P stops at the stacking operation position R2, the negative foil 1 is placed on the pallet P by the negative foil placement device 11A at intervals between the intermittent operations of the turntable 6.

  Here, first, in the storage section 12 of the negative electrode foil placing apparatus 11A, the suction section 17 of the transport device 14 that has suctioned the negative electrode foil 1 is guided onto the pallet P. Subsequently, the suction unit 17 is lowered while the negative electrode foil 1 is being adsorbed, and the negative electrode foil 1 is placed on the pallet P. Then, the suction unit 17 stops in a state where the negative electrode foil 1 is pressed downward (the pallet P).

  When the pallet P moves to the stacking operation position R2, the blank portion K is stopped at the first stop position X1 (pressing position) (see FIG. 8). Then, when the negative electrode foil 1 is placed on the pallet P, each holding member 31 rises. As a result, the pressing claw 42 moves up to the height position regulated by the regulating piece 38 of the suction portion 17.

  Subsequently, each of the holding members 31 rotates to pivot the negative electrode pressing claw 42A to the first stop position X1 (see FIG. 4). When the negative electrode pressing claw 42A moves to the first stop position X1, each holding member 31 moves down. Thereby, the vicinity of each of the four corners of the negative electrode foil 1 is pressed by the negative electrode pressing claws 42A.

  When the four corners of the negative electrode foil 1 are pressed by the negative electrode pressing claws 42A, the suction by the suction part 17 is stopped, and the suction of the negative electrode foil 1 is released. Note that the same applies to the following lamination operations, but the timing of the suction stop (release of the sheet body) by the suction unit 17 does not depend on the above timing, and the suction unit 17 presses the sheet body downward, May be at any time after the state in which does not cause a position shift or the like.

  Thereafter, the suction section 17 is raised, and the turntable 6 is rotated by 30 °, so that the pallet P moves to the stacking operation position R3. During this time, the state where the vicinity of each corner of the negative electrode foil 1 is pressed by the negative electrode pressing claws 42A is maintained.

  When the pallet P stops at the stacking operation position R3, the separator 2 is mounted on the stacked body 4 on the pallet P by the separator mounting device 11B in the interval between the intermittent operations of the turntable 6.

  Here, first, the suction part 17 of the transport device 14 that has suctioned the separator 2 in the storage part 12 of the separator mounting device 11B is guided onto the pallet P. Subsequently, the suction unit 17 is lowered while the separator 2 is being suctioned, and the separator 2 is placed on the negative electrode foil 1. Then, the suction unit 17 stops in a state where the separator 2 is pressed downward (negative electrode foil 1). Here, the edge portion (protruding portion) of the separator 2 that protrudes outward from the peripheral edge portion of the suction portion 17 is put on the negative electrode pressing claw 42A that presses the negative electrode foil 1.

  When the separator 2 is placed on the negative electrode foil 1, each holding member 31 rises. As a result, the pressing claw 42 moves up to the height position regulated by the regulating piece 38 of the suction portion 17. Then, at the first stop position X1, the negative electrode pressing claw 42A slightly lifts from the negative electrode foil 1 while lifting the edge of the separator 2.

  Subsequently, each holding member 31 rotates, and the negative holding claw 42A is turned to the second stop position X2. At the same time, the negative electrode upper separator pressing claw 42B pivots from the fifth stop position X5 so as to be replaced with the negative electrode pressing claw 42A at the first stop position X1 (see FIG. 5).

  When the negative electrode upper separator holding claw 42B moves to the first stop position X1, each holding member 31 descends. Thus, the vicinity of each of the four corners of the separator 2 is pressed by the negative electrode upper separator pressing claw 42B. In such a state, the suction by the suction unit 17 is stopped, and the suction of the separator 2 is released.

  Thereafter, the suction unit 17 is raised, and the turntable 6 is rotated by 30 °, so that the pallet P moves to the stacking operation position R4. During this time, the state where the vicinity of each corner of the separator 2 is pressed by the separator pressing claws 42B on the negative electrode is maintained.

  When the pallet P stops at the stacking operation position R4, the positive foil 3 is placed on the laminate 4 on the pallet P by the positive foil placing device 11C at intervals between the intermittent operations of the turntable 6.

  Here, first, the suction unit 17 of the transport device 14 that has suctioned the positive electrode foil 3 in the storage unit 12 of the positive electrode foil placing device 11C is guided onto the pallet P. Subsequently, the suction unit 17 is lowered while the positive electrode foil 3 is being adsorbed, and the positive electrode foil 3 is placed on the separator 2. Then, the suction section 17 stops in a state where the positive electrode foil 3 is pressed downward (the separator 2). Here, the edge portion of the positive electrode foil 3 that protrudes outward from the peripheral edge portion of the suction portion 17 is put on the negative electrode upper separator pressing claw 42B that is pressing the separator 2.

  When the positive electrode foil 3 is placed on the separator 2, each holding member 31 moves up. As a result, the pressing claw 42 moves up to the height position regulated by the regulating piece 38 of the suction portion 17. Then, at the first stop position X1, the negative electrode upper separator pressing claw 42B slightly lifts from the separator 2 while lifting the edge of the positive electrode foil 3.

  Subsequently, each holding member 31 rotates, and pivots the negative electrode upper separator holding claw 42B to the second stop position X2. At the same time, the positive electrode pressing claw 42C pivots from the fifth stopping position X5 to the first stop position X1 so as to be replaced with the negative electrode upper separator pressing claw 42B (see FIG. 6).

  When the positive electrode pressing claw 42C moves to the first stop position X1, each holding member 31 moves down. Thus, the vicinity of each of the four corners of the positive electrode foil 3 is pressed by the positive electrode pressing claws 42C. In such a state, the suction by the suction unit 17 is stopped, and the suction of the positive electrode foil 3 is released.

  Thereafter, the suction unit 17 is raised, and the turntable 6 is rotated by 30 °, so that the pallet P moves to the stacking operation position R5. During this time, the state where the vicinity of each corner of the positive electrode foil 3 is pressed by the positive electrode pressing claw 42C is maintained.

  When the pallet P stops at the stacking operation position R5, the separator 2 is placed on the laminate 4 on the pallet P by the separator placing device 11D at intervals between the intermittent operations of the turntable 6.

  Here, first, the suction part 17 of the transport device 14 that has suctioned the separator 2 in the storage part 12 of the separator placing device 11D is guided onto the pallet P. Subsequently, the suction unit 17 is lowered while the separator 2 is being suctioned, and the separator 2 is placed on the positive electrode foil 3. Then, the suction unit 17 stops in a state where the separator 2 is pressed downward (the positive electrode foil 3). Here, the edge portion of the separator 2 that protrudes outward from the peripheral edge portion of the suction portion 17 is placed on the positive electrode pressing claw 42 </ b> C pressing the positive electrode foil 3.

  When the separator 2 is placed on the positive electrode foil 3, each holding member 31 moves up. As a result, the pressing claw 42 moves up to the height position regulated by the regulating piece 38 of the suction portion 17. Then, at the first stop position X1, the positive electrode pressing claw 42C slightly lifts from the positive electrode foil 3 while lifting the edge of the separator 2.

  Subsequently, each holding member 31 rotates, and the positive electrode pressing claw 42C is pivotally moved to the second stop position X2. At the same time, the positive electrode upper separator pressing claw 42D pivots from the fifth stop position X5 to the first stop position X1 so as to be replaced with the positive electrode pressing claw 42C (see FIG. 7).

  When the positive electrode upper separator holding claw 42D moves to the first stop position X1, each holding member 31 moves down. As a result, the vicinity of each of the four corners of the separator 2 is pressed by the separator pressing claws 42D on the positive electrode. In such a state, the suction by the suction unit 17 is stopped, and the suction of the separator 2 is released.

  Thereafter, the suction unit 17 is raised, and the turntable 6 is rotated by 30 °, so that the pallet P moves to the stacking operation position R6. During this time, a state where the vicinity of each corner of the separator 2 is pressed by the positive electrode upper separator holding claw 42D is maintained.

  When the pallet P stops at the stacking operation position R6, the negative foil 1 is mounted on the laminate 4 on the pallet P by the negative foil mounting device 11E at intervals between the intermittent operations of the turntable 6. Note that the work content at the stacking work position R6 is the same as the work content at the stacking work position R2, and thus detailed description is omitted.

  However, in the stacking operation position R6, after the positive electrode upper separator holding claw 42D pivots from the first stop position X1 to the second stop position X2 (see FIG. 8), it does not stop at the second stop position X2. Subsequently, the vehicle turns to the third stop position X3 (see FIG. 4). That is, the blank portion K pivots from the fifth stop position X5 to the first stop position X1, and then continuously pivots to the second stop position X2 without stopping at the first stop position X1. As a result, the negative holding claw 42A is turned from the fourth stop position X4 to the first stop position X1 without stopping at the fifth stop position X5 so as to be replaced with the blank portion K.

  When the four corners of the negative electrode foil 1 are pressed by the negative electrode pressing claws 42A, the suction of the negative electrode foil 1 by the suction part 17 is released. Thereafter, the suction unit 17 is raised, and the turntable 6 is rotated by 30 °, so that the pallet P moves to the stacking operation position R7. During this time, the state where the vicinity of each corner of the negative electrode foil 1 is pressed by the negative electrode pressing claws 42A is maintained.

  When the pallet P stops at the stacking operation position R7, the separator 2 is mounted on the stacked body 4 on the pallet P by the separator mounting device 11F at intervals between the intermittent operations of the turntable 6. Note that the work content at the stacking work position R7 is the same as the work content at the stacking work position R3, and thus a detailed description is omitted.

  When the four corners of the separator 2 are pressed by the separator pressing claws 42B on the negative electrode, the suction of the separator 2 by the suction part 17 is released. Thereafter, the suction unit 17 is raised, and the turntable 6 is rotated by 30 °, so that the pallet P moves to the stacking operation position R8. During this time, the state where the vicinity of each corner of the separator 2 is pressed by the separator pressing claws 42B on the negative electrode is maintained.

  When the pallet P stops at the stacking operation position R8, the positive foil 3 is mounted on the laminate 4 on the pallet P by the positive foil mounting device 11G at intervals between the intermittent operations of the turntable 6. Note that the work content at the stacking work position R8 is the same as the work content at the stacking work position R4, and thus detailed description is omitted.

  When the four corners of the positive electrode foil 3 are pressed by the positive electrode pressing claws 42C, the suction of the positive electrode foil 3 by the suction unit 17 is released. Thereafter, the suction section 17 is raised, and the turntable 6 is rotated by 30 °, so that the pallet P moves to the stacking operation position R9. During this time, the state where the vicinity of each corner of the positive electrode foil 3 is pressed by the positive electrode pressing claw 42C is maintained.

  When the pallet P stops at the stacking operation position R9, the separator 2 is placed on the laminate 4 on the pallet P by the separator placing device 11H at intervals between the intermittent operations of the turntable 6. Note that the work content at the stacking work position R9 is the same as the work content at the stacking work position R5, and thus a detailed description is omitted.

  When the four corners of the separator 2 are pressed by the separator pressing claws 42D on the positive electrode, the suction of the separator 2 is released, and the suction part 17 rises. Thereafter, as the turntable 6 intermittently rotates by 30 °, the pallet P sequentially moves to the blank position R10, the take-out work position R11, the blank position R12, the take-in work position R1, and the stacking work position R2. During this time, the holding member 31 does not operate, and the state where the vicinity of each corner of the stacked body 4 (separator 2) is pressed by the positive electrode upper separator holding claw 42D is maintained.

  When the pallet P stops at the stacking operation position R2, the stacking process of the second round is started. However, in the laminating process of the second and subsequent rounds, unlike the start of lamination, when the positive separator press claw 42D pivots at the lamination work position R2, the positive separator press claw 42D moves from the first stop position X1 to the first stop position X1. (3) The turning movement is performed to the stop position X3. That is, the negative electrode pressing claw 42A pivotally moves to the first stop position X1 without the blank portion K stopping at the first stop position X1.

  Thereafter, the turntable 6 is repeatedly rotated, and the above-described laminating step is repeatedly performed a predetermined number of times, thereby completing the laminated body 4 in which the negative electrode foil 1, the separator 2, the positive electrode foil 3, and the separator 2 are repeatedly stacked in order from the bottom. .

  Then, when the pallet P on which the completed laminate 4 is placed is stopped at the unloading operation position R11, each holding member 31 is rotated, and the positive electrode upper separator holding claw 42D is turned to the second stop position X2. Let it. As a result, the blank portion K is turned to the first stop position X1 so as to be replaced with the positive electrode upper separator pressing claw 42D. In this state, the pallet P on which the completed laminate 4 is placed is taken out of the turntable 6 by the take-out work section 9. The removed pallet P is sent to a subsequent process by the removal work section 9.

  As described in detail above, according to the present embodiment, the transport device 14 (the suction unit 17) that transports and holds the sheet body to the pallet P is provided, and the “negative electrode pressing claw 42A” that presses the negative electrode foil 1 and the negative electrode foil 1, a "positive separator pressing claw 42B" for pressing the negative electrode upper separator 2, an "positive electrode pressing claw 42C" for pressing the positive electrode foil 3, and a "positive electrode upper pressing claw 42D" for pressing the upper separator 2 of the positive electrode foil 1. Are provided separately.

  With this configuration, the active material (for example, the positive electrode active material) adhered when the predetermined pressing claw 42 pressed one electrode foil (for example, the positive electrode foil 3) adheres to the other electrode foil (for example, the negative electrode foil 1). There is no fear.

  Further, in the present embodiment, since all four corners of the sheet member are pressed down, any one of the four corners of the sheet member is turned up, and the next sheet member is stacked in a bent state. Can be suppressed.

  Furthermore, in the present embodiment, all four corners of the sheet body are simultaneously released in a state where the sheet body is pressed by the suction unit 17, and after the sheet body is once flattened, the sheet body is pressed. In addition, the occurrence of wrinkles and bending can be suppressed.

  In addition, since the sheet member can be pressed uniformly over a wider range by the suction portion 17, the above-described operation and effect can be further enhanced, and the sheet member is less likely to be displaced.

  Further, in the present embodiment, when a new sheet member is placed (when the presser claw 42 is switched), the corner portions are located near the four corners of the sheet member already placed thereunder. The tip 43 of the pressing claw 42 that has pressed one of the two sides (side parallel to the side α of the stacking stage S) at the first stop position X1 has at least one of the two sides. The swiveling movement is performed so as to pass over the other side (side parallel to the side β of the stacking stage S).

  As a result, if a newly bent sheet body is bent downward at a corner thereof, or a corner of a sheet body already placed under the newly bent sheet body is bent upward. In this case, the bending operation can be straightened by the turning operation of the holding claw 42. As a result, a reduction in product quality can be suppressed.

  In the present embodiment, the “negative electrode pressing claw 42A”, the “negative electrode pressing claw 42B”, the “positive electrode pressing claw 42C”, and the “positive electrode The pressing claws 42D "are arranged in this order. Thus, each time the sheet members are stacked, the sheet members can be pressed by the dedicated holding claws 42 only by sequentially rotating the shaft portion 40 in one predetermined direction. As a result, the operation control can be simplified, the switching operation of the presser claw 42 can be speeded up, and the production efficiency can be improved.

  In addition, in the present embodiment, a regulating piece 38 that adjusts the amount of rise of the holding claw 42 is provided in the suction unit 17 of the transport device 14. As a result, a new sheet body is placed on the laminated body 4 pressed by the holding claws 42, and when the holding claws 42 are raised, the height position at which the holding claws 42 rise is set to the height of the stacked body 4. It can be adjusted according to the height.

  As a result, for example, even in the initial stage of the stacking process in which the height of the stacked body 4 is low, the relative amount of rise of the pressing claw 42 with respect to the upper surface of the stacked body 4 can be relatively reduced. Since the lifting amount of the pressing claw 42 is reduced, the degree of curving of the edge of the sheet body placed on the pressing claw 42 can be reduced. That is, the sheet body can be stacked on the stacked body 4 without significantly deforming the sheet body placed on the pressing claw 42. As a result, the quality of the laminate 4 can be improved.

  Further, in the present embodiment, the height adjusting means (the regulating piece 38 and the like) of the pressing claw 42 is provided in the suction unit 17 of the transport device 14. Thereby, it is possible to realize a constant rising amount of the pressing claw 42 with reference to the upper surface of the stacked body 4 with a simpler configuration. In addition, since the regulating piece 38 operates together with the suction portion 17, it is not necessary to separately provide a driving means for height adjustment, and the number of components can be reduced and the configuration can be simplified.

  In addition, since the height adjusting means (the regulating piece 38 and the like) of the holding claw 42 is provided separately from the turntable 6 that is driven to rotate, wiring of signal lines and the like is not complicated, and wiring is easy. And simplification can be achieved. In addition, since the weight of the turntable 6 can be reduced, a decrease in the operability of the turntable 6 can be suppressed, and a decrease in productivity can be suppressed.

  Further, it is not necessary to provide the height adjusting means (the regulating piece 38 and the like) of the holding claw 42 in correspondence with each of the twelve lamination stages S arranged on the turntable 6, and the eight laminations for performing the lamination work are not required. Since it is sufficient to provide them in correspondence with the working positions R2 to R9, it is possible to reduce the number of parts, simplify the configuration, and reduce the number of installation locations.

When the suction portion 17 is lowered, the operation piece 87 comes into contact with the restriction piece 83, and at the same time, the restriction piece 83 is driven against the tensile force of the coil spring 86 to be pushed down to a predetermined height position.

  With the above configuration, similarly to the above-described embodiment, it is possible to adjust the rising amount of the holding claw 42 with reference to the upper surface of the stacked body 4 on which the sheet conveyed by the suction unit 17 is placed. Further, since it is not necessary to separately provide a driving unit for moving the operation piece 87, the number of components can be reduced and the configuration can be simplified.
